Figure 3. Oxygen saturation (%) as a function of depth.

Figure 3

Clear oxygen under-saturation exists below 60 m, which is a signature of the upper halocline water (UHW)16. This signature is formed in the Chukchi Sea as Pacific winter water and locally formed shelf bottom water by mineralization of organic matter16.
